What type of bug are you reporting? Teambuilder
What is the bug?
Antique / Artisan forms of Sinistea and Poltchageist respectively are illegal in National Dex formats, despite the evolved versions of the alternate forms being legal.
Are you able to replicate it? If so, how?
Go into the builder, select an ND format (i tested with OU, Ubers UU, and LC), the forms are marked as illegal and won't validate with reasoning "does not exist in the National Dex.".
